To determine what's wrong, u need to have the codes read. If the light is coming on, it is a signal that something is wrong w/ the emissions system. A code is stored in the cars computer that will indicate what the problem is. Most parts stores will read the stored engine codes for free. They plug a scan tool into a port under the dash to retrieve the code(s). Write them down, and ask what u should do to correct the problem. If u have any further questions after that, u can post them here. Let me know how u make out.

Scan for check engine codes, sounds like you are having a misfire problem. Common causes include clogged fuel filter, weak fuel pump, worn out spark plugs, failing sensors, weak ignition coils or spark plug wires....etc.

Pontiac Montana SV6 engine chugs at 80 Kms

It is usually coming from the spark plug wires( leak spark). Spark to ground or piece of metal.
To find out exactly take an empty spray bottle fill her up with water and add 2 tablespoons of salt. With the engine running a light spray of the mix on spark plug wires you will see the spark leak and proof the spark plug wires have a defect. if so replace all spark plug wires that should solve your problem.

Hope it helps.

1997 Oldsmobile Achieva - check engine light is on and car is running sluggishly...brand new motor installed 6 weeks ago.

What speed are you going when it chugs?
It could be as simple as a bad spark plug or a spark plug wire/boot grounding out.
When spark plug boots get old, the rubber cracks and lets voltage arc out the side and to the engine instead of through the plug.
This will be most noticeable when trying to maintain a speed of over 40 mph, or under mild acceleration.
The reason for being noticeable at this speed/acceleration level is that the transmission torque converter will be locked, transferring the vibration from any engine miss straight through to the wheels.
